Wall Mounting
STEP 1: Mounting the TN-4500A to a wall requires 4 screws. Use the toughness switch as a guide to mark the correct positions of the 4 screws.
STEP 2: Use the 4 screws in the wall-mounting kit. If you would like to use your own screws, make sure the screw head is between 6.0 mm and 7.0 mm in diameter and the shaft is less than 4.0 mm in diameter, as shown on the right.

Do not screw the screws in all the way—leave a space of about 2 mm to allow room for sliding the ToughNet switch between the wall and the screws.
NOTE Before tightening the screws into the wall, make sure the screw head and shaft size are suitable by inserting the screw through one of the keyhole- shaped apertures of the ToughNet switch.

STEP 3: Once the screws are fixed in the wall, hang the ToughNet switch on the 4 screws through the large opening of the keyhole-shaped apertures, and then slide the switch downwards.
Tighten the four screws for added stability.

NOTE To provide greater protection from vibration and shock, use screws with shaft diameter between 6.0 mm and 7.0 mm, and fix the ToughNet switch onto the wall directly through the large opening of the keyhole-shaped apertures.
NOTE TN-4500A Series switches have passed IP42 certification. To achieve the IP42 protection, only use upright panel/wall mounting installation. Water sprayed at an angle of up to 15° degrees from the vertical will not damage the product (as indicated in the following illustration).

Wiring Requirements

WARNING
Turn the power off before disconnecting modules or wires. The correct power supply voltage is listed on the product label.
Check the voltage of your power source to make sure you are using the correct voltage. Do NOT use a voltage greater than what is specified on the product label.
These devices must be supplied by a SELV source as defined in the Low Voltage Directive 2006/95/EC and 2004/108/EC.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your Moxa switch. This device has UL 61010-2-201 approval. Use copper conductors only, 75°C, and tighten to 4.5 pound-inches. For use in pollution degree 2 environments.
ATTENTION
Safety First!
Observe all electrical codes dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.

Please read and follow these guidelines:

• Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.
  NOTE: Do not run signal or communications wiring and power wiring through the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.

• You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.

• Keep input wiring and output wiring separated.

• It is strongly advised that you label wiring for all devices in the system when necessary.

Grounding the ToughNet Switch
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the grounding screw to the grounding surface prior to connecting devices.

ATTENTION
To ground this product to earth, use a green and yellow AWG 16 or higher grounding cable.
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface such as a metal panel.

Connecting the Power Supplies
The toughness TN-4500A Series switches support dual power inputs power input 1 and power input 2. The M23 6-pin male connector on the TN-4500A Series switches’ front panel is used for connecting dual power inputs.
The M23 power connector uses 5 of the 6 pins for dual power input and chassis grounding.

2| PWR1 / DC –| Connect “PWR1 Neutral / DC -” to the negative (-) terminal when using a DC power source.
3| Chassis Ground| Connect the “Chassis Ground” to the equipment ground bus for DC inputs.
4| PWR2 / DC –| Connect “PWR2 Neutral / DC -” to the negative (-) terminal when using a DC power source.
5| PWR2 / DC +| Connect “PWR2 Live / DC +” to the positive (+) terminal when using a DC power source.

STEP 1: Plug your power cord connector into the power input port of the TN-4500A switch.
STEP 2: Screw the nut on your power cord connector into the power input connector on the switch to ensure a tight connection.

ATTENTION
Before connecting the TN-4500A Series to the power input, make sure the power source voltage is stable.
ATTENTION
Do not power on the TN-4500A Series before connecting the M23 connector.

Connecting the Relay Outputs
Each TN-4500A Series switch has two sets of relay outputs—relay output 1 and relays output 2. The M12 A-coded 5-pin male connector on the TN-4500A Series’ front panel is used for the two relay outputs. Use a power cord with an M12 A-coded 5-pin female connector to connect the relay contacts. You can purchase an M12 power cable from Moxa;
the model number is CBL-M12 (FF5P)/OPEN-100 IP67.

Pinouts for the relay output port on the TN-4500A Series

N.C.: Not connected
FAULT:
The two sets of relay contacts of the M12 A-coded 5-pin male connector are used to detect user-configured events. The two wires attached to the fault contacts form an open circuit when a user-configured event is triggered. If a user-configured event does not occur, the fault circuit remains closed.

Connecting the Data Lines
10/100BaseT(X) Ethernet Port Connection
All TN-4500A Series models have 12 or 24 10/100BaseT(X) Ethernet ports (M12 D-coded 4-pin female connector). The 10/100TX ports located on the TN-4500A Series front panel are used to connect to Ethernet-enabled devices. Most users configure these ports for Auto MDI/MDI-X mode, in which case the port’s pinouts are adjusted automatically depending on the type of Ethernet cable used (straight-through or cross-over), and the type of device (NIC-type or HUB /Switch-type) connected to the port. In what follows, we give pinouts for both MDI (NIC-type) ports and MDI-X (HUB/Switch-type) ports. We also give cable wiring diagrams for straight-through and cross-over Ethernet cables.

ATTENTION
The protective cover must be fixed properly to ensure IP42 protection. Use a torque wrench set to a torque of 4 kgf-m when tightening the screws. Note that applying a larger torque may damage the plastic protective cover.

Bypass Relay Function

The TN-4516A-4GTXBP, TN-4516A-12PoE-2GPoE-2GTXBP, and TN4528A-16PoE-2GPoE- 2GTXBP models have 2 to 4 Gigabit ports equipped with bypass relay functionality. When the switch is operating normally, these Gigabit ports work in the same way as the other ports. That is, frame ingressions are processed and then forwarded. In the event the switch stops working due to a power failure, the bypass relay function will be triggered to ensure non-stop data communication.
The figure below illustrates the bypass relay function. For example, if Switch B loses power, then the Gigabit ports will be bypassed through the relay circuit and the transmission line from Switch A to B and the transmission line from Switch B to C will interconnect automatically. The bypass relay function helps the network recover from single-node failures in a linear topology.

With the maximum segment length of category 5 twisted-pair cable being 100 meters, cable length must be considered when designing a network that utilizes this function. For example, the total length of the cables from Switch A to B and from B to C must be no more than 100 meters. This way, if the two adjacent nodes (switch B and C for example) encounter a power failure, there will be no stoppage, provided that the total length of the cables A-to-B, B-to-C, and C-to-D are no more than 100 meters.
The bypass relay function works best for networks with linear topologies. ToughNet™ switches with bypass relay functions are not recommended to be used in networks that employ ring topologies because network loops may occur when redundancy protocols such as RSTP or TurboRing™ are applied.
